The tweet may have been somewhat ill-timed, and poorly thought-out, given the current "heightened tensions" with Syria. Either way, apparently some oil traders either skipped over or didn't understand the hashtag reference to "YomKippur73" (and the reference to the Soviet Union -- a country that hasn't existed in decades) and interpreted the tweet to mean that Israel was bombing Syria today. And, in response they started bidding up the price of oil. Because twitchy commodities dealers apparently do their pricing based on tweets.

Of course, the article notes that traders eventually realized their mistake... but the price of oil stayed up, rising over a dollar from $110.40 a barrel to $111.50 a barrel, and then continuing to rise a bit (though more slowly) after the mistake was understood. Isn't it great that key pieces of the global economy can change based on some people totally misreading a tweet? Makes me feel so comfortable about the state of the world today.
